CRUDE-OIL BURNER.

SPECIFICATION forming part of Letters Patent No. 612,118, dated October1 1, 1898A. Application filed August 18,1897. Serial N0- 648,7l8. (Nomodel.)

To all whom it may concern:

Be it known that I, CHARLES HENRY MYERS, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented la new and useful Crude- Oil Burner, of which the following isa specification.

This invention relates to hydrocarbon-burners, by which either crude orrefined petroleum may be converted into vapor and consumed; and theobject of the invention is to provide a burner of this character of simple construction by which the oil will be converted into vapordirectly at the point of ignition and without passing through aheatingchamber, whereby the burner will be rendered more eficient inoperation, will not be liable to become choked or to otherwise get outof order, and which may be easily Akept clean.

The invention will be fully described hereinafter and the novel featuresthereof clearly defined in the claims.

In the drawings, Figure i1 is a front elevation of a heating-stove,partly broken away to show my improved burner in position. Fig. 2 is avertical section through the baseplate, the burner, and the spreader.Fig. 3 is a plan view of the burner. Fig. 4 is a bot,- tom plan view ofthe generating-ring. Fig. 5 is a perspective view of a spreader designedfor use in cook-stoves.

Similar reference-nu merals indicate similar parts in the severalfigures.

1 indicates a heating-stove, which may be of any ordinary or approvedconstruction; 2, the base-plate, provided with a central opening 3,below which the burner 4 is supported, as will be hereinafter described.As shown in the drawings, the burner is circular in plan view andprovided at its edge with a series of perforated ears or lugs 5, thepurpose of which will be referred to hereinafter.

The lower surface of the body of the burner is convex, and at the centerthereof a boss 6 is provided which is bored vertically to form a chamber7, the outer end of which willbe preferably threaded interiorly, asindicated by 8, in order to receive the threaded end of the oil-supp1ypipe 9, which will lead from an elevated reservoir. (Not shown.) It isvobvious that the supply-pi pecan be attached to the burner in any othersuitable manuel', if preferred.

On the upper face of the body of the burner two concentric troughs areformed, the inner trough being indicated by 10 and the outer trough by11. The outer trough 11 is semicircular in cross-section and is intendedto receive the oi1,which must be initially burned in order to heat thegenerating-ring sufficiently to convert the oil into vapor, and also toreceive any oil that may pass out from below the generating-ring withoutbeing vaporized -and also all extraneous and non-convertible matterwhich may be carried to the burner by the oil. i 12 indicates a postextending vertically from the central portion of the burner and formsone of the boundary-walls of the trough 10. This trough is alsosubstantially semicircular in cross-section, but will preferably beprovided with a shallow annular recess 13 in its bottom, the purpose ofwhich will be referred to hereinafter. A series of passages 14 radiatefrom the inner end of the chamber '7 and open out into the bottom of thetrough 10, and these passages convey the oil from the chamber' 7`anddistribute it uniformly in the troughlO at equidista'nt points. Inpractice I have found that four of these passages are sufcient, but suchnumber may be increased or diminished without departing from the spiritof my invention.

15 indicates the generating ring, which when it becomes heated convertsthe oil which 'is delivered into the trough 10 into vapor. This ringlits over the post 12, is supported in the trough 10, and provided witha series of grooves 16 in the lower outside portion of its periphery,which grooves form passages for the vapor that is generatedby the heatedring. The grooves terminate at their upper ends at the upper edge of theannular iiange 17, which divides the troughs lO and 11, and the vapor isignited at'this point.

In using oil for fuel in heating or cooking stoves it is necessary thatthe ordinary grate be removed and the imperforate base-plate 2substituted-that is, the plate is imperforate with the exception of thecircular opening 3 immediately above the burner. The burner IOO issecured to the plate below it by means of bolts 18, which pass throughopenings in the plate adjacent to the edge of the opening 3 and throughthe perforated ears 5 on the burner, and the burner is spaced apart fromthe plate by the sleeves 19, which t over the bolts and engage the lowerface of the plate and the upper faces of the ears 5. When secured inproperposition, the post 12 will partly project through the opening inthe plate 2, but the flame will issue from the burner below the plate,and the air necessary for combustion will pass from all sides of theburner between the plate and the upper face of the burner and bethoroughly mixed with the vapor as it issues from the burner, andthereby insure perfect combustion.

20 indicates the spreader, which may be detachably supported on the topof the post in any suitable manner.

In Fig. 5 I have illustrated a spreader which is designed for use incook-stoves and, as shown, is in the form of an open-ended rectangulartrough. verted and removably supported on the top of the post 12 andwill deiiect the llame in each direction and cause it to issue from itsopen ends and below the griddles of the stove. By using a deiiector ofthis construction a single burner only will be inserted in thecook-stove.

In operation the oil will flow from the reservoir through the pipe 9into the chamber 7 and be distributed through the radiating passages 14into the trough 10, from which it will overflow into the trough 1l.Asbestos or some other suitable absorbent material will be placed in thetrough 11 to form a wick in order that the oil in the trough 11 may beignited, and the burning oil will gradually heat the generatingring 15and also the burner in immediate contact with it, and as soon as theburner and the ring are sufticiently heated the oil which flows into thetrough 10 will be converted into vapor, which will issue out through thegrooves 16 and be ignited at the edge of the annular flange 17. Inpractice I have found it is preferable to form the shallow recess 13 inthe bottom of the trough 10 in order that the oil can be more quicklydistributed in a thin iilm entirely around the bottom of the trough andbe brought into contact with the generatingring 15 throughout itsent-ire circumference. While, however, this shallow recess ispreferable, it is not absolutely necessary, as in practice I haveattained good results when the recess has been absent, although at timesthe ilame has not been entirely uniform around the burner, and for thisreason it is preferable to form the recess in the bottom of the trough10.

It will be seen that the oil-passages are entirely below the llame, andconsequently the oil in its passage to the burner does not become heatedto any appreciable extent until This trough will be in` generating-ring.One of the principal advantages, therefore, of my burner is that the oilis delivered from the reservoir to the generating-ring practically cold,and as soon as it is brought into contact with the generatingring in athin film it is immediately converted into vapor and consumed.

In some burners of which I am aware the oil is conveyed to a chambermore or less remote from the point at which the vapor ignites andbecomes gradually heated in its passage through the chamber until itreaches the point where it is converted into vapor. This gradual heatingof the oil in a measure refines it and the residuum of `the oil willaccumulate on the Walls of the heated chamber to such an extent as toeventually and in a veryshort time choke the chamber,and thereby renderthe burner inoperative until the chamber is cleaned out. Very frequentlyit is impossible to get at the interior of the chamber to cleanse it,and in such cases an entirely new chamber, or the part of the burnercontaining the chamber, has to be provided. In my burner the oilisconverted into vapor directly at the point of ignition, and as the vaporrushes out through the grooves in the generating-ring anynon-convertible matter contained in the oil will be carried with it andfall into the outer trough, from which it can easily be removed. Intesting my burner with crude oil which contained a quantity of sand thesand was carried with the oil into the burner beneath thegenerating-ring and blown out by the vapor and deposited in the outertrough.

From the foregoing description it will be seen that I have produced anexceedingly simple and inexpensive burner which is not liable to becomechoked or to otherwise get out of order and which can be easily cleaned.

It will be understood that changes in the form, proportion, and theminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is- 1. In ahydrocarbon-burner, a burner-body having an oil-supply connection at itslower side and formed in its upper face with an annular trough, an oilinlet or inlets leading from the oil-supplyconnection to said trough,and a horizontally-arranged generating-ring lying in said trough andresting directly on the body over the oil inlet or inlets7 substantiallyas set forth.
